"We will be expanding the Nearby Pokémon feature to the rest of
the continental United States and large parts of Europe,"
according to a Wednesday
blog post by Niantic. "We will continue to review the
feedback submitted on our official social media accounts and in
other channels and make changes if necessary."

The tracker allows you to see where Pokémon are located in the
game's map based on their proximity to nearby Pokéstops, which
are virtual stops for collecting items that are associated
with physical locations in the real world.

Without the tracker, many have been left to blindly
stumble upon Pokémon in the game for months. Some
players on Reddit have been having trouble with the new tracker's
accuracy, but those issues are hopefully fixed now that Niantic
is making it available to everyone.
